Rights, Action, and Social Responsibility: Public debates surrounding immigration policy, climate change, international relations, and constitutional and human rights are currently at the forefront of our national discourse. Critical reasoning, supported through academic research is needed. As a result, De Gruyter, along with its partner presses, is making freely available books and journal articles across nine topical areas for all students and faculty. Broadening access to this scholarship enables more people to address these issues in an informed manner: it helps us combat false news sources, to consider the nature of truth and ethics, and to understand the struggles of all members of society
Surveying Natural Populations is a user-friendly primer to the essential methodologies of quantitative field ecology or paleoecology. Combining the intuitive methods of the field researcher with the mathematical precision of the statistician, the volume determines, through real biodiversity and ecological examples, the necessary measures for a complete community assessment while clarifying the confusions between biological and statistical terminology. Focusing on underlying mathematical concepts, it describes how to complete incrementally a quantitative sampling of any recent or fossil population. The first half of Surveying Natural Populations explains the fundamentals of ecological assessment. Employing a single data set throughout, initial chapters navigate such topics as estimating densities, relative abundance, occurrences, the determination of adequate sample sizes and field sampling schemes. The second half covers the newest advances in biodiversity measurement. Through the use of information mathematics and decomposition, the authors mathematically examine the relationship among a number of proposed diversity indices and discard inappropriate measures. What remains is a simple, all-encompassing system called SHE analysis, in which species density, richness, information, and evenness are all shown to be related explicitly. This biodiversity data is then integrated into a simple graphic, a plot called a biodiversitygram, which provides the researcher with a cohesive descriptive and inferential tool to assess any community's biodiversity
